- My invention relates to dynamo-electric machines, especially those of the inductor type, now well known in the art; and it consists in the general type of machine by which I obtain a novel and useful apparatus, as Well as, in a more specific sense, improved details of construction which I have devised,by which the first cost of the machine maybe largely reduced, in that I am enabled to use va less number of eld-coils and field-magnet cores, and also to some lextent-to employ standard forms of apparatus made from patterns suitable for dynamos of other constructions.
- my improved dynamo a field-m agnet of ordinary type--that is, having inwardly extending.,r laminated polepieces provided with ordinary windings.
- the pole-pieces Isomewhat extend circumferentia1ly,and upon these extended polefaces I mount the armature-coils of the machine. Adjacent to these coils, which may of course be connected in any suitable relation to obtain current of one or more phases, the inductor revolves.
- the indnctor In most inductor-dynames the indnctor consists'of a bobbiu-like structure, in section somewhat like the letter H, composed of two star-Wheels connected at their centers by a central body or shaft, about which a coil may be wound to determine the polarity of, the" mass.
- Each of those starwheels is ofdifferent polarity-that is to say, all thc projections on one are of north polarity and all on the other of south polarity, each one being provided with its own stationary armature, the' two armatures being'mounted My improved inductor dii'ers from those just described in that theinductor, although a single unitary structure, is when stationary of north polarity on one side of its diameter and of south polarity on the other side, the plane of division passing through its-axis of tor I.
- FIG. 1 is a side elevation of 65 my improved machine withl one of the bear- -ings removed; Fig. 2, an end elevation, partly in section, upon the line 2 2 of Fig. l.
- Fig. 3 is a diagram o f the electric circuits.
- Fig. 4 is a sketch illustrating the .magnetic paths of 7o the machine, and Fig. 5 is a modified form. y I
- A is the base of the machine
- B is the fieldmagnet frame.
- C C are the bearings for the armature.
- Pole-pieces D D in the case illustrated for a four-pole machine are lalso provided with suitable field-magnet coils D' D, surrounding the pole-pieces.
- the polar-'faces F F are extended circumferentially partly, around the revolving inductor.
- K is the shaft of the machine, to which is 8o keyed a suitable spider carrying the induc- G G are the' projecting arms of the induct-o'', by the motion of which past the armaturecoils a ditl'erenceof magnetic condition is produced.
- the armaturefcoils la' b'c' are disposed.
- I have shown -a threephase machine, and there are six coils disposed upon eaeh polar face; y .l 9o
- a e are the leads .from the' armature-coils, and a' b' eare the armature-coils themselves.
- the order ofeonnection is best secu by tracing the connection of a seriesof coilsfor in- 9 5
- the coil a' -being mo'st nearly adjacent to the inductor, is connected to the coil a, which is on the under layer, while a is upon the upper layer. a.”

- An induetor-dynamo comprisinga iieldmagnet having projecting pole-pieces,ppole faces circumferentiall-y extended, the armasumed in excitation.. and the eliiciency thus ture-coils-being mountedv 'upon the polar faces, and a revolving inductor.
- An inductor-dynamo having inwardly- ⁇ extendinggpole-pieces, polar faces provided with projections, and armature-coils mounted upon the projections of the polar faces.
- Aninductor-dynamo comprising a fieldmagnet having inwardly extending polepieces of alternately-opposite polarity, arma ⁇ ture-coils mounted upon the polarfaces of the field-magnets, and a revolving inductor havingprojections v'passing througlrthef fields created bythe ,eld-magnet poles.
